AODD Pump Applications Across Industry
Diaphragm pumps handle some of the most challenging fluids in UK industry. Here’s how they’re used across the sectors we serve.
Chemical Processing
AODD pumps are ideally suited to chemical applications because they can be built entirely from non-metallic materials — polypropylene or PVDF bodies with PTFE diaphragms and valve balls handle the most aggressive acids, alkalis and solvents without corrosion.
Key advantages in chemical processing: no mechanical seals to fail, safe handling of flammable fluids (earthed metallic pumps), ability to run dry without damage, and simple maintenance without specialist tools.
Recommended brands: Debem, Blagdon, Tapflo, ARO, Verder
Food & Beverage
Food grade AODD pumps use FDA-compliant wetted materials — stainless steel or polypropylene bodies with Santoprene or PTFE diaphragms. They transfer viscous foodstuffs, oils, syrups, beverages and dairy products gently without shear damage.
Key advantages: no oil lubrication that could contaminate product, easy CIP/SIP cleaning, gentle pumping action for shear-sensitive fluids, and ATEX versions available for flammable ingredients.
Recommended brands: Flotronic, Graco, ARO, Tapflo, Verder
Water Treatment
Water treatment plants use AODD pumps for chemical dosing (chlorine, ferric sulphate, polymer), sludge transfer and effluent handling. The pumps’ ability to handle solids-laden liquids and their resistance to treatment chemicals makes them the standard choice.
Recommended brands: ARO, Blagdon, SandPIPER, Tapflo
Paint & Coatings
Graco built its reputation on paint and coatings applications, and AODD pumps remain dominant in this sector. Solvent-resistant materials handle lacquers, varnishes and two-pack coatings. Earthed aluminium pumps are used for flammable solvent-based products.
Recommended brands: Graco, ARO, Blagdon, Versamatic
Pharmaceuticals
Pharmaceutical manufacturing demands validated, hygienic fluid handling. PTFE-lined AODD pumps with electropolished stainless steel bodies and clean-room-compatible materials are used for active ingredient transfer, solvent recovery and filling operations.
Recommended brands: Dellmeco, Depa, Flotronic, Verder
Waste Handling
Abrasive slurries, contaminated liquids and solids-laden waste streams are where AODD pumps truly excel. Unlike centrifugal pumps, they handle high solids content without damage and can pass particles up to the valve ball diameter. For sludge and slurry applications, AODD pumps are the default choice.
Recommended brands: SandPIPER, Depa, ARO, Blagdon
